AXLE-NUT WRENCH.

SPECIFICATION forming part of Letters Patent No. 613,613, dated November1, 1898.

Application filed December 24, 1897. Renewed October 4,1898. Serial No.692,651. (No model.)

To aZZ whom it may concern:

Be it known that I, DANIEL WARNER, a citizen of the United States,residing at Bronson, in the county of Branch and State of Michigan, haveinvented a new and useful Axle-Nut Wrench, of which the following is aspecification.

The invention relates to improvements in axle-nut wrenches.

The object of the present invention is to improve the construction ofaxle-nut wrenches and to provide a simple, inexpensive, and efficientdevice adapted to engage an axle-nut and the hub of a wheel and toadjust itself automatically to the size of the nut and the opening ofthe hub and capable of firmly gripping the parts, so that the nut may bescrewed on or off the axle by rotating the wheel.

Another object of the invention is to provide a device which willprevent an axle-nut, after it has been unscrewed from the axle,

from dropping upon the ground.

The invention consists in the construction and novel combination andarrangement of parts, as hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure l is a perspective view of an axle-nut wrenchconstructed in accordance with this invention and shown engaging a huband an axle-nut. Fig. 2 is a perspective view of the wrench detached.

Like numerals of reference designate corresponding parts in both figuresof the drawlngs.

1 designates an axle-n u't wrench comprising a pair of similar jaws 2and a substantially U-shaped spring 3, having diverging sides which areadapted to be compressed when the device is applied to a wheel, asillustrated in Fig. 1 of the accompanying drawings, whereby the jawswill be caused to engage and grip the interior of the hub firmly. Thespring is constructed of resilient material sufficiently stout toproduce the necessary pressure or frictional engagement between the jawsand the hub 4.

Each jaw, which is constructed of suitable metal, is substantiallysegmental, being pro vided at its straight edge with a central V-shapednotch 5, adapted to engage the corner of a nut, as shown in Fig. 1, andthe curved edge or periphery of the segmental jaw is provided atopposite sides of the spring 3 with teeth 6 and 7, shouldered inopposite directions and adapted to bite the inner face of the hub. Oneset of teeth positively engages the hub and prevents the device fromslipping when the wheel is rotated in one di rection, and the other setof teeth secures the necessary engagement of the parts when the wheel isrotated in the opposite direction.

The wrench is capable of adjustment to suit the diameter of the hub andthe size of the nut, and after the latter has been unscrewed from theaxle the wrench prevents it from dropping into the dust.

The invention has the following advantages: The axle-nut wrench isexceedingly simple and inexpensive in construction and is adapted toadjust itself automatically to the hub of a wheel and an axle-nut, andit is capable of engaging both the nut and the interior of the hub, sothat the former may be screwed on or 0E its axle by simply rotating thewheel. The device also retains the nut in the hub and prevents the samefrom falling upon the ground when removed from the axle. The

arrangement of the sets of teeth secures the necessary engagementbetween therperipheries of the jaws and the interior of a hub.

Changes in the form, proportion, and minor details of construction maybe resorted to without departing from the spirit or sacrificing any ofthe advantages of this invention.

What I claim is 1. A device of the class described comprispair ofsegmental jaws connected to the arms In testimony that I claim theforegoing as of the spring and provided at their periphmy own I havehereto aifixed my signature in eries with teeth, the teeth at one sideof each the presence of two Witnesses.
